Questions & Step-by-Step Solutions
A cyclist is moving at a speed of 15 km/h. If a car is moving in the same direction at 30 km/h, what is the relative speed of the car with respect to the cyclist?
Step 1: Identify the speed of the cyclist, which is 15 km/h.
Step 2: Identify the speed of the car, which is 30 km/h.
Step 3: Since both the cyclist and the car are moving in the same direction, we can find the relative speed by subtracting the speed of the cyclist from the speed of the car.
Step 4: Perform the subtraction: 30 km/h (car) - 15 km/h (cyclist) = 15 km/h.
Step 5: The result, 15 km/h, is the relative speed of the car with respect to the cyclist.
Relative Speed – Relative speed is the speed of one object as observed from another object, calculated by subtracting their speeds when they are moving in the same direction.
